Q14 ResPas option
Function
ResPas is the term used for a class of systems that improve the dynam-
ic properties of the TopCon power supplies. In particular, the energy
present in the load can be dissipated more quickly with a ResPas sys-
tem and therefore permits quicker reactions, even with reactive loads.
In case of an excessively high output voltage the discharge device
switches an additional load to the output. This feature can reduce over-
shooting, e.g. on load shedding.
The discharge device is operated via a binary signal that is sent from
the TopCon power supply to the discharge device.
Normally the discharge device can be integrated into the TopCon power
supply. However, very high power discharge device resistors must be
positioned externally (depending on the load and requirement).

The intervention of the discharge device is signalled by the flashing of
the Power LED on the front of the TopCon power supply.
